RIBBON REEL Application filed September 19, 1929. Serial N 0. 393,611.

fastening means so that the reel can be quick- 1 .ly taken apart for packing and shipping or for the replacement of an injured or broken art.

p A further object of this invention is the provision in a. motion picture reel of a central hub of molded material.

A still further object of this invention is to employ cadmium plating. for the metal parts of the reel.

These and other objects, as will appear from the following disclosure, are secured by means of this invention.

This invention resides substantially in the combination, construction, arrangement, and relative location of parts all as will be described more fully below.

Referring to the drawing Figure 1 is a side elevational view of a reel employing features of this invention;

Fig. 2 is a vertical cross-sectional view taken on the line 2-2 of Fig. 1;

Fig. 3 is an enlarged detailed cross-sectional View of any two of the spokes with the hub removed showing howthe clips are secured to the spokes; and

Fig. 4 is a perspective view of one of the" clips.

The motion picture art in particular now demands a so-called knock-clown reel which may readily be taken apart for repair and replacement and for reduction in bulk for F packing and shipping. Among other things,

one of the features of this invention involves a reel constructlon comprising three maJor elements which may be quickly assembled or disassembled. Another feature of the invention is the rigidity and trueness of the reel when assembled notwithstanding the fact of a molded material, such as bakelite and necessity of having the reel true is impor- I operation. A molded central-hub-of this type that itis a reel of the knock-down type. An additional feature of the reel is the central hub portion on which the film is wound up. In this case the central hub portion is made similar products. The advantage of a ceno5 tral molded hub is that it may be made practically absolutely true in formand its outer surface may be made very smooth so that c it does not scratch or'mark the film. The 60 tant, is known in the art, since in rewinding a reel it is often revolved at avery high rate of speed as the film is removed therefrom. An additional feature of the 65 invention involves the plating of all the metal parts with cadmiumwhich we have found of great importance since the chemicals of the ii-lm do not tarnish or corrode this plating material. 7

These and other below are novel to this invention.

Referring to the drawing, the reel is shown comprising a-centr'al hollow spindle I having transverse slots in each'end extending 7 longitudinally thereof for as'ho-rt distance; These slots, of course engage the pin on the spindle of the motion picture machine which receives the reel so that it may be positively driven. The surface of the spindle Inear the center is knurled, as at 3', so that it firmly grips the molded central hubwh-ich is formed therearound. The molded central hub comp-rises a series of flat, thin, radiat ing' arms 4 which terminate in the end in arcuate sections 5 which together form a complete interrupted cylinder. The slots between the sections are intended to receive the end of the film at the start of the winding featureswhich will appear has advantages, as pointed out, such as'tru'eness' in form, smootl'i-ness of surface, ind-if ferenc'c to temperature changes and moisture conditions, lightness, and similar advantages. Each side of the reel comprises a wire skeleton form of a ring of wire 6 having a series of radial spokes 7 welded thereto at one end and welded at the other end to the center discs 8'. These 7 center discs have central holes through which-the ends of the spindle 1 project. Secured to adjacent pairs of spokes on one skeleton frame are the clips 9 which have a hole therethrough, and secured to the other skeleton frame are the clips 10 which have a raised central boss which is internally threaded. When the skeleton frames are slipped into. place over the central spindle they are secured firmly in place by means'of bolts ll which extend through the holes in clips 9 and engage the threads of clips 10. The clips are secured. to the Y spokes by integraltabs 12 which are bent around the spokes to substantially encircle them at the points of contact, as shown in Fig. 3. The spokes of the skeleton frames lie in notches on theedge ofthe arcuate portions 5. Each clip is provided with a right angle flange which serves to strengthen the structure. As pointed out before theplating of the metal parts with cadmium render them impervious to the action of the chemicals veloping.

used in the film and in itsiprinting and dc.- lVhen. the bolts 11 are removed the reel breaks up into three parts, comprising the central molded hub and the two skeleton side frames and, of course, the bolts.

It will be apparent to those skilled in the art from the foregoing disclosure that we have embodied certain principles of construction in a ribbon reel whichmay be varied without departing therefrom. We do not,

therefore, desire to be strictly limited to the structure given for purposes of illustration posed of side members each comprising a Wire ring, a central portionand radiating spokes secured thereto, a slotted drum positioned between said side members and provided with means for engaging the spokes thereof, and clip members for clamping said drum in .assembled position.

In testimony whereof we have hereunto set our hands on this seventeenth day of Septemher A. 30., 1929.

but rather to the spirit and scope of the appended claims. I 7

What we seek to secure by United States Letters Patent is: 4

1. A reel of the type described consisting of a hollow central spindle, a. molded central drum securedto said spindle and having an I interrupted cylindrical surface, side frame members, and means for securing the side frames to the molded drum.

' 2. A wire reel of the type described composed of side members each comprising a wire ring, a central portion, and radiating spokes secured thereto, clip members fastened to each pair of adjacent spokes, a molded drum, andbolts connecting said clip members to holdthe said side members and said drum together. 7 V I 3. In a reel, a central molded drum having an interrupted periphery and a hollow central spindle, side frames comprising wire rings, center pieces and wire spokes secured together, clips firmly secured to each pair of adjacent spokes, and bolts extending through the drum and engaging said clips for holding the frame members securely to the central drum. V

4. A reel comprising a hollow metal spindle, a drum molded thereon having ra diating arms terminating in arcuate members which together form an interrupted cylinder, wire side frames, and means for. securing the its
